黒川研究室は、シリコンを主材料とした太陽電池と関連デバイスの高性能化に取り組んでいます。研究の中心は、シリコン表面の電子的欠陥を低減する「パッシベーション層」の設計・最適化です。酸化チタンや酸化シリコン、ナノ結晶シリコンなどの薄膜材料を用いて、シリコン界面の欠陥を効果的に終端し、太陽電池の変換効率を高める方法を探求しています。これらの研究では、プラズマ処理や水素化、原子層成膜などの実験的手法と、分子動力学シミュレーションを組み合わせて、材料の構造と電気特性の関係を詳細に調べています。さらに、表面テクスチャーの設計や光の吸収効率改善、ペロブスカイト・シリコン積層型太陽電池の開発にも注力しています。厚さが薄いシリコン基板での近赤外光の吸収を改善するため、ナノインプリント技術によって作製した特殊な光トラップ構造を検討しています。加えて、ベイズ最適化という機械学習手法を導入し、膨大なプロセスパラメータの組み合わせから効率的に最適条件を見出す方法も展開しています。このほか、シリコンナノワイヤーのリチウムイオン電池応用、熱電素材としてのマグネシウムシリサイド、SiC電子デバイスの信頼性向上、摩擦発電デバイスなど、シリコンおよび関連半導体材料の多様な応用分野にも研究を拡張しています。
